2.5" --> 3" Down Pipe (pics)
Just finshed converting my 2.5" revhard dp to bolt up to my 3" thermal exhaust. It is a lot quieter that i thought it was gonna be. Not sure why other folks 3" thermals are so loud, it may be the addition of a 3" flex section before my cat the helped quiet it down.
See my sig for more pics...

the 3" flex section is from JCWhitney and costs $66. the original DP is a $140 rev hard 2.5" unit.
the flex section and the cat are tig welded into a single unit with a 3" flange at both ends. i didnt weld the flex section to the DP as i want to keep them separate so i can ceramic coat the DP.
i measured and cut all the pieces and a buddy of mine tig welded them, i gotta say tig is the only way to go. i used to take my stuff to meineke and it would look like they spat chewing gum on the joints.
if anyone in houston needs this kind of stuff done drop me an IM or email. I will get you intouch with the guy who can do all this stuff for you.

reducer is from summit racing.
flex section and flanges are from jc whitney.
all are avaialble locally for ~40% more cash, just call any muffler shop.

Re: 2.5" --> 3" Down Pipe (FredoSP)
are all the five bolt flanges for the t3 discharge the same bolt up pattern?
im talking about tha 5 bolts themselves, do one t3 flanes for external fit another turbo? and is there a way to get 3" on right from the beginning?
looks really good

it is a debated point but its generally accepted that you cant fit a 3" DP on with A/C.
